Note about hw.vga.textmode: this tunable has no meaning for UEFI - first = of all, there is no API to change to VGA text mode in UEFI, secondly, = there may or may not be VGA (firmware) at all. We only do land in kernel = with linear framebuffer mode active and all we have is information about = that mode (FB address, size and color bits). In *worst* case, it is = actually even possible that we only have UEFI API for boot loader and no = linear framebuffer for kernel. distorted console after kernel start means that either the kernel efifb = driver does something wrong, or the console device gfx mode change did = happen but the FB driver was not properly informed about the fact. rgds, toomas > On 28 Nov 2018, at 11:51, O.
